Gen FUKATSU 4cc9bd2eaa [ARM] 3789/4: Fix VFP emulation to ignore VECITR for scalar instruction
VECITR in Floating-Point Exception register indicates the number of
remaining short vector iterations after a potential exception was
detected.

In case of exception caused by scalar instructions, VECITR is NOT updated.
Therefore emulation for VFP must ignore VECITR field
and treat "veclen" as zero when recognizing scalar instructing.

Daniel Jacobowitz 0355b3e039 [ARM] 3750/3: Fix double VFP emulation for EABI kernels
Patch from Daniel Jacobowitz

vfp_put_double didn't work in a CONFIG_AEABI kernel.  By swapping
the arguments, we arrange for them to be in the same place regardless
of ABI.  I made the same change to vfp_put_float for consistency.

Daniel Jacobowitz 7c6f25141b [ARM] 3748/3: Correct error check in vfp_raise_exceptions
Patch from Daniel Jacobowitz

The recent fix to hide VFP_NAN_FLAG broke the check in vfp_raise_exceptions;
it would attempt to deliver an exception mask of 0xfffffeff instead of reporting
a serious error condition using printk.  Define a safe constant to use for
an invalid exception maskm, and use it at both ends.

Russell King 438a761679 [PATCH] ARM: Fix VFP to use do_div()
VFP used __divdi3 64-bit division needlessly.  Convert it to use
our 64-bit by 32-bit division instead.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
